Among the narrations that deal with voluntary charity is the following:
1 – The Messenger of Allah ﷺ said: “Charity extinguishes the Lord’s anger and wards off an evil death.” Al-Tirmidhī transmitted it and graded it ḥasan.
I say: the scholars have challenged this evaluation and did not accept his grading, for al-Tirmidhī relates it (2/23) through the chain of ʿAbd-Allāh ibn ʿĪsā al-Khazzāz, from Yūnus ibn ʿUbayd, from al-Ḥasan, from Anas, traced back to the Prophet. He then remarked, “A ḥasan gharīb ḥadith.”
This ʿAbd-Allāh—whose kunya is Abū Khalaf—is unanimously judged weak; no one declared him reliable. Because of that, the scholars faulted al-Tirmidhī for calling the report ḥasan. In Fayḍ al-Qadīr, ʿAbd al-Ḥaqq states:
“He did not explain what prevented it from being sound; its defect lies in the weakness of its transmitter Abū Khalaf—that is, al-Khazzāz—for he is repudiated in ḥadith. Ibn al-Qaṭṭān therefore held: the report is weak, not ḥasan.”
Al-ʿIrāqī likewise ruled it weak, and Ibn Ḥajar noted that Ibn Ḥibbān, al-ʿUqaylī, Ibn Ṭāhir, and Ibn al-Qaṭṭān all criticised it, while Ibn ʿAdī said: “He is not corroborated in it.” The same appears in Fayḍ al-Qadīr.
The ḥadith suffers from another flaw as well: al-Ḥasan al-Baṣrī narrates it with an ambiguous “ʿan” (ʿanʿanah), and he was known for practicing tadlīs. Both Ibn Ḥajar al-ʿAsqalānī, in his list of mudallis transmitters, and Ibn al-ʿAjmī class him among those widely recognised for tadlīs.
The report is also cited in Irwāʾ al-Ghalīl, 885, where I have discussed it in detail.
